Specification of Letters Patent.

Patented Apr. 6, 1915.

Application filed December 14, 1914. Serial No. 877,172.

T all whom it may concern:

Be it known that we, JOHN A. HOAR and GEORGE WV. HOAR, citizens of the United States, residing at Oskaloosa, in the county of Mahaska and State of Iowa, have mvented certain new and useful Improvements in Railway-Gates, of which the following is a specification, reference bemg had to the accompanying drawings.

This invention relates to certain improvements in railway gates and has relation more particularly to a device of this general character under control of the rolling stock; and an object of the invention is to provide a gate of this kind having novel and 1mproved means whereby the same is automatically caused to assume a closed position when the rolling stock has come into predetermined proximity thereto and whereby the gate is caused to assume an open position after the rolling stock has passed a predetermined distance therebeyond.

Furthermore, it is an object of the invention to provide a novel and improved device of this general character wherein the gate is under control of members positioned at predetermined points at opposite sides of the gate and adapted to be operated by the rolling stock, and it is also an object of the invention to provide a gate of this general character having novel and improved means whereby the operating mechanism is so controlled as to cause the gate to be maintained in closed position during the time the roll ing stock is between the controlling members, hereinbefore referred to.

It is also an object of the invention to provide a gate of this general character having novel and improved means whereby vehicles or the like which may be passing over the track-way at the time the gate is lowered may be free to pass clear of the track-way.

The invention consists in the details of construction and in the combination and arrangement of the several parts of our improved gate whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novelfeatures of the invention will be carefully defined in the appended claims. In order that our invention may be the better understood, we will now proceed to describe the same with reference to the accompanying drawings, wherein Figure l is a fragmentary elevational View, somewhat diagrammatic, illustrating a railway gate constructed in accordance with an embodiment of our invention the upper extremities of the road gates being broken away; Fig. 2 is a top plan view of the device as illustrated in Fig. 1; Fig. 3 is an enlarged fragmentary view in plan of a gate member illustrating in detail the sup plemental gate comprised therein; Fig. 1 is a fragmentary side elevational view, illustrating the hinged connection of the supplemental gate; Fig. 5 is a view, partly in top plan and partly in section, illustrating additional details with regards to the supplemental gate; Fig. 6 is an enlarged view, partly in rear elevation and partly in section, of a gate structure as herein embodied; Fig. 7 is an enlarged fragmentary view, partly in side elevation and partly in section, of the structure as illustrated in Fig. 6; Fig. 8 is a fragmentary View, partly in elevation and partly in section, illustrating the operating structure for the gate, as herein embodied, but in a position different from that shown in Fig. 7 Fig. 9 is a sectional view taken substantially on the line 99 of Fig. 6; Fig. 10 is a sectional view taken substantially on the line 10-10 of Fig. 6, with the parts shown in a different adjustment; Fig. 11 is a fragmentary view in elevation of the controlling lever herein embodied; Fig. 12 is an elevational view, detached, of the operating lever, herein embodied, and which is adapted to coact with the controlling lever; Fig. 13 is an enlarged fragmentary elevational view illustrating a trip member with which the rolling stock is adapted to coact; Fig. 14 is a view in top plan of the trip member as illustrated in Fig. 13; Fig. 15 is a sectional view taken substantially on the line 1515 of Fig. 13; Fig. 16 is an elevational view, detached, of a supporting plate employed in connection with the trip member as herein embodied; Fig. 17 is an elevational view, detached, of the trip member as herein disclosed; and Fig. 18 is an elevational view, detached, of the clutch member adapted to coact with the trip member.

As disclosed in the accompanying drawings, R denotes the rails comprised in a track-way and with which a gate structure V V to be particularly illustrated in Figs. 7 and] 9. For reasons which are believed to be selfor structures G constructed and operated in accordance with an embodiment of our invention may coact. 'In Figs. 1 and 2, We I have disclosed. four gate structures, but as the construction thereof is identical, it is be-v lieved that a detailed description of one will suflice. I Y

As herein set forth, each gate structure comprises the spaced supporting members 1 substantially A-shape and having their upper extremities tied or connected by the shafts 2 and 3 having suitably aflixed there-.

to, respectively, the road gate 4 and the sidewalk gate 5. In order that the shafts 2 and 3 may rotate in unison and in proper direct'ions, said shafts are provided with the 1ntermeshingsegmental gears 6, as is bel eved evident, the inner or lower extremity of the gate 4 is provided with the counter-balancing weight Tcapable of adjustment longitib dinally thereof. We also find it of advantage to havethe outer extremity of the gate 4 comprising a section 8 hingedly connected,

as at 9, with the gate 4 proper and provided with the rearwardly disposed tail portion 10 adapted to overlie the gate 4 proper whereby movement of the section 8 inone direction is limited,- yet permitting .free movement of the section 8 in an opposite. di-

rection so that a vehicle or the like which; may be upon the 'trackway at'the time the gate is lowered is free to pass therefrom.

We also find it of advantage to have coact ing with the section 8, the spring member 11 which serves normally to maintain the section 8 substantially in 'alinement with the gate 4, as is particularly shown in Fig. 3/

Fixed to the shaft 2 and projecting there-. from is a rock arm 12 having its outer extremity in pivotal engagement with an elongated member 14 telescopically engaged with a tubular member 15; The lower ex-- tremity of the member 15' is in pivotal engagement, as at 16, with a controlling lever 17 mounted for rocking movement intermediate its lengtharound a shaft 18 suitably supported by the members 1, or more particularly the cross braces 19 thereof. The up per extremity of the member 14 is provided with an outstandinglug 20 to which is suit-- ably secured an extremity of a retractable member 21, the opposite or lower extremity whereof being suitably secured to a laterally disposed lug. 22 carried by the lower extremity of thetubular member l5. The retractable member 21 is of such a tension that upon" initial downward movement be-' ing imparted to the tubularmember 15, the rock'arm 12 will be pulled downwardly under the influence of the member 21 and thus adjust the gates 4 and 5 into closed position.v

. In order to retard the speed at which the gates 4 and 5 travel in assuming their closed positions, we pivotally engage, as indicated at 23, with one of the supporting members 1 the cylinder 24 in which is-mounted for sliding movement the piston 25 having'affixed thereto, the operating stem 'or rod 26 in pivotal engagement with a second rock arm 27 fixed. to the shaft 2. The lower-extremity of the cylinder 24 has in communication therewith the' regulatable valve 28 in communication with the atmosphere and whereby the. rate of travel of the gates 4 and 5 may be readily and conveniently adjusted in a manner which is believed to be self-evia dent. The downward movement; of the controlling lever 17 also results in the expansion of the retractable member 29 having one extremity secured to a lug 30 projecting from the lower portion 'of the tubular member 15 and having its opposite extremity secured toa lug 31 depending from a sleeve 32 loosely mounted on the shaft 2.

The downward movement of the controlling lever 17 is 'of such extent as to; bring the lower extremity -3 3 thereof into operative engagement with the spring pressed latch member loosely mounted upon the shaft 35 operatively supported by the members '1" and whereby it will be readily perceived that the gates 4 and 5 will be maintained in their "closed adjustment until the latchff34 has been disengagedfrom the end portion 33 :of the controllinglever 17. Thelresult ant expansion ofthe'. retractable member 29 e 7 upon'downward movement of the lever- 17 is such as to create suflici'enttension upon.

release of the latch from thejcontrolling lever 17 as to cause the gates 4 and 5 to return to their open, and a's'herein disclosed,

vertical positions; In order to assure this 1 latteryoperation of the gates, it is to be,ob served that the memberlll is provided with an'annular shoulder 14 with which they ad jacent extremity of the tubular memberfl5 coacts, as'is believed tobe particularlyfillustrated in Fig. 7.

The hub portion 36 of the lever 17 is provided with a clutch face 37' withfwhi ch is assume the position shown in Fig. 8 and as has been hereinbefore set forth.

I length upon the' shaft 18 and thefaces 37 and 38 are adapt-.

ner that upon ro- I l As herein embodied, the requisitemove v ment is imparted to the lever 40-by the trip members the side of a rail at located relative to the gate and .operatgively engaged with the lever '40 through the inc-- dium of the flexible connections 42, herein disclosed as formed ofwire of propergage'l As herein disclosed, the members 42 are en- 41 pivotally supported adjacent points predeterminedly gaged with the opposite extremities of the lever 40 and the rock lever 43 fixedly secured intermediate its length to the shaft 44 operatively supported by the bearing 45 positioned to one side of the adjacent rail R and by the bearing 46 carried by the plate 47 clamped against the web of the rail R, as is particularly illustrated in Fig. 15. The trip lever 41 is loosely mounted upon the shaft 44 and is provided with a hub 48 having a clutch face 49 adapted to coact with the clutch member 50 fixed to the shaft 44 whereby it will be perceived that upon depression of the trip member or lever 41 in one direction, the lever 40 will be correspondingly rotated around the shaft 18 and result in the requisite or desired movement of the controlling lever 17. The trip lever or member 41 is normally maintained in a vertical or upright position through the medium of the equalizing springs 50, as particularly illustrated in Figs. 13 and 14, said springs being secured at their inner extremities to the upper end portion of the trip lever or member 41 and at their opposite extremities to the lugs 51 projecting laterally from a rail R at predetermined distances at opposite sides of the shaft 44. The trip lever or member 41 is of such a length as to project above the head or tread of the rail R and is provided with the roller 52 rotatable around a horizontal axis 53. As is believed to be self-evident, the roller 52 is adapted to be engaged by the wheels of the rolling stock passing over the rail R and which contact results in the desired depression of the lever 41.

\Vhile it is obvious that the movement of the trip member or lever 41 in one direction will result in the downward movement of the lever 17, it will also be observed that upon downward movement of the lever or member 41 in an opposite direction, the resultant movement of the lever 40 will cause the latch 84 to become disengaged from the lever 17 owing to the contact of the stop 54 with the latch member 34, as is indicated in Figs. 7 and 8. As herein disclosed, the stop 54 is carried by the elongated member 55 pivotally engaged as at 56 with the upper end portion of the lever 40 and having its free or outer extremity disposed through an opening 57 produced through the latch member 34.

From the foregoing description, it is thought to be obvious that a railway gate constructed in accordance with our invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that our invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason we do not wish to be understood as limiting ourselves to the precise arrangement and formation of the several parts herein shown in carrying out our invention in practice.
